The NSK 7210CTRDULP4Y is a super precision angular contact ball bearing supplied as a matched duplex pair, part of the NSK 7200 Series designed for high speed and high accuracy spindle applications. The bearing has a 50 mm bore, 90 mm outside diameter, and 20 mm width per bearing, with a 15 degree contact angle and DUL (universal back to back or face to face) matched arrangement. The P4 designation indicates ISO Class 4 precision tolerance, suited to machine tool spindles, grinding spindles, and other rotating equipment where minimal runout and stable high speed performance are required. Construction includes a phenolic resin cage and high grade steel rolling elements with super finished raceways. Published NSK specifications list a dynamic load rating of 45,000 N and a static load rating of 31,500 N per bearing, with maximum speeds of 16,500 rpm under grease lubrication and 25,000 rpm under oil lubrication, and an operating temperature limit of 120 degrees C. Typical applications include CNC machining center spindles, lathe spindles, milling spindle assemblies, grinder headstocks, and industrial high speed rotating equipment. Each unit is supplied in original NSK packaging with carton labeling reading 7210CTRDULP4Y and the NSKHPS designation associated with the high performance super precision line. Item is new old stock; the box has been opened for inspection and the bearings remain unused. Suitable as a direct replacement for matched duplex sets cross referenced from the NSK 7210CTRDULP4Y part number on machine tool spindle assemblies and equivalent OEM specifications.
